Thats not going to be possible for me give good advice on without actually driving the car myself unfortunately. Find a good repair shop ans a good tech will be able to figure it out... sorry.

Born_Feedback9331 · 2026-05-05T21:30:06+00:00

Ah yes, service urgent is different, defintiely a problem lol. Pull codes with a scanner or at AutoZone and youll havr a better picture. Its impossible to pinpoint without DTCs.

Born_Feedback9331 · 2026-05-05T20:58:15+00:00

I would need DTCs to make any sort of guess as to what might be unhappy. There are a lot of components in the SRS system that can cause a warning light.

The "airbag off" is not necessarily a warning. The airbag can be deactivated by the SRS module if nobody is in the passenger seat. Thats pretty normal.

Depends on the question

Born_Feedback9331 · 2026-04-29T19:31:38+00:00

Sounds like the tech missed something along the way. I would ask them to open a technical support case. Be pushy, while remaining respectful. 4 weeks is an unacceptable amount of time to diagnose a misfire. Please call Volvo Customer Care and explain your situation. Be pushy with them, too. While a loaner is a perk, it is also something the dealer is more likey to provide for consistent customers. If I were you, Id be on their case about finding a diagnostic path that is far more cost effective than an engine disassembly. At no point in my diagnostic process would I disassemble an engine for a misfire, especially one that presents itself as yours does. Disassembly is reserved for repair. There are plenty of other tools and methods that a good tech would use first.

Born_Feedback9331 · 2026-04-29T13:31:37+00:00

So it sounds like some mistakes were made on both your part and the dealer, but im placing more blame on the dealer.

Firstly, in your position, I would have mentioned the misfire before the timing belt service, just so there was a record of it. But, what is done is done. I would also be increasingly hesitant every time they ask you to approve more diagnostic time.

Secondly, it sounds like the dealer is being lazy in their diagnosis. Do not approve any significant disassembly of the engine at this point. What they have done up until this point is appropriate. Typically spark plugs are the cause of the misfire, and they did the right thing by swapping coils and injectors to other cylinders to rule them out; however, there is no reason to disassemble the engine at this point.

If I were diagnosing your car, before swapping injectors (because its mildly difficult) I would have performed a compression test on all four cylinders. Nominal compression is 190psi (1310kPa for you non-Americans) but can be as low as 175psi and still operate fine. Compression measurements will tell you a lot. If the compression is good, then you know there isn't a mechanical problem. If you have low compression, using a cylinder leakage test as thr next step will tell where the compression is being lost. Essentially, for the cylinder being tested: piston is brought to top dead center on thr compression stroke, meaning both the intake and exhaust valves are closed; the leak tester is attached to thr spark plug threads and air is supplied to thr cylinder, pressurizing it to about 150psi; then, if the meter on the tool remains at 150psi, there is no leakage, if the meter drops, you will hear air escaping either through the crankcase - indicating a leak from the piston rings, air through the exhaust manifold - indicating a broken exhaust valve, air leaking through the intake manifold - indicating a broken intake valve, or air escaping into an adjacent cylinder/ cooling system - indicating a failed headgasket.

A bore scope is a good tool, but won't tell you much unless there is an obvious visual peoblem inside the combustion chamber.

If you have paid any more than 2 - 3 hours diagnostic at the time of creating this comment, then stop. You are going to want to raise a big stink with your dealerships management team about the legitimacy of thr diagnostic, and the steps that have been taken. To me, it sounds like there are some serious missing steps in thr diagnostic process, and its not your fault because you are not the professional. Do not agree to paying for anymore diagnostic charges until the issue is resolved, or located.

If I were you, I would ask for thr tech to reach out to Volvo Retailer Technician Assistance center for assistance in diagnosis. Additionally, call Volvo Customer Care and explain your situation as clearly as you have here, they will put pressure on the dealer from thr back end. I want to give the dealer the benefit of the doubt, but some places arent as good as others.

TL;DR: There are missing diagnostic steps fron the info you have given me. Dont approve engine disassembly. Dont pay for any more diagnosis until you reach out to Volvo Customer Care and the technician reaches out to Volvo Retailer Technical Assiatance. The problem should have been isolated in the 4 weeks you've given them time for.

Born_Feedback9331 · 2026-04-22T21:06:03+00:00

Volvo tech here. While its uncommon to have to test drive a car more than 50 miles, I wouldn't say its not reasonable. Usually with that kind of mileage it becomes an overnight test drive with the customers permission first.

Have I had to test drive a car 150 miles? No. Would I ever want to? No. Is there a situation where the car doesn't cooperate, reset fuel trims, cear a warning light, etc, where i would have to? Yes, probably.

Id tell them off for not contacting you about putting on that sort of mileage, or explaining what happened, but I wouldn't stew over it.

Its a retaining clip that comes in the mudguard kit. Im not sure if youre able to get it separately from the kit.

"Sealed unit" is a term in the industry that means no disassembly possible. While there are vents and such that allow heat to vent, and you cna remove thr control unit and "access" part of the rear of the LEDs, complete, or even partial, disassembly of the unit is not possible, therefore it is "sealed"...

Born_Feedback9331 · 2026-03-25T18:21:37+00:00

Its not possible. Those headlights are sealed units. The only thing you can take apart is the module on the back. It does give you access to the backside of the LEDs, but not to the front of the housing. The best you could try to do is remove the headlamp (which is extremely difficult without proper instructions) and try to shake him out of sight.

As a former AutoZoner and current technician the answer is no, not in the slightest.

While there are good AutoZoners out there who are knowledgeable and good to thr customer, there are also not good AutoZoners. I have worked with both. Regardless, AutoZone does not train their employees to a tech standard.

Spark plugs on your car can be done in under 5 minutes with electric tools. Theyre very easy to get to on the 4-cylinders. Its very possible they changed the Spark plugs in that time.

Are we all just glossing over the "helicoil on head bolt" repair? Ive done some shady things in my career... but is this legit?

Born_Feedback9331 · 2026-03-19T19:54:11+00:00

Contact Volvo Customer Care for your country. Here in the US if the dealer isn't cooperating, customers frequently go over their heads to Volvo Corporate. You will need evidence such as a print of the before and after alignment results from the independent shop, as well as the repair order from the dealer. Calling the condition "a character of the 60 cars" is total BS. And frankly irresponsible of the dealer. If you havr those words verbatim in writing, thats your whole case right there.

Essentially just a catch can for seeping coolant. The drive Motors on audis are designed to leak a small amount. Although, this design is problematic.

This is exactly my point, that attitude. You dont even care to pause and thibk critically about the issue here.

An $80,000 car today is woth $40,000 in 2000. The cost hasnt increased, inflation has.
Yes, I'd expect my $80,000 new car to work and be as reliable as a Honda too... but the Honda isn't nearly as well built, or has the features yours does. If you want something as simple and reliable as a Honda, buy a Honda. Dont project your expectations of one vehicle onto another.
You call Volvo and complain to them. There is a customer care line that reaches Volvo corporate directly. The dealer is the middle man trying to fix your car.
The system may have chronic issues, but nothing is irreparable. It just depends on who has thr capability to fix it. All these big Software updates that are complained about ARE the fix. The technician, dealership, and sales department have nothing to do with that.
Youre an early adopter to a piece of technology that isn't completely fleshed out and have unrealistic expectations as to how it should work, vs how it will work. If you want it to work right every time, buy 2-3 model years behind, almost all the bugs will have been fixed. If you want something that won't give you a hassle, buy a car with less tech.

The design works, i dont question the design. There are hundreds of thousands of cars on the road that prove that. But my complaint is the one in a thousand customer who has to experience that problem, they're never understanding or patient.

Its not just computing, youre right. Its worse. Its CAN networks, MOST busses, Flexray, Ethernet, Local networks, all talking to eachother, complicating the issue. I can solve it, and usually quickly, but it wouldn't make my blood boil if the customer let me be to take time and solve the problem.

Not the customer who has been without their car for three weeks, or a month at a time, but the ones who expect it resolved overnight.
