That would be the most difficult pipe to access with an AWD. I was thinking this when mine failed when I put the motor together 3 years ago. I ended up buying a new pipe as the old one had been disturbed by constant re-insertion and trying to line up the gasket on the other end. Darn expensive littl...

To answer the question I believe the 1995 onward engines will be a match. Strictly speaking if you swap out the sensors with your own on a 1995 you should be fine. The notable difference is that they increased the timing belt width to 28mm (up from 25mm in the 1994 model) and associated pulleys and ...

The first thing that happens when a coilpack fails is you get a rotten egg smell from the exhaust. I always have an ELM327 plugged into the OBDII port coupled with the Torque App so if a coilpack fails I pull the corresponding injector plug to prevent un-burned fuel going through. At $5 each for a c...

That part above is not part of the oil filler assembly on your car. I bet you just need one of these: It goes under the oil filler cap and is removed with a pick tool

Without pulling coils/plugs to see what they fitted (regular plugs or something fancy) and how they fitted them it's just a guessing game, though if this fails to find the problem it's still a guessing game. The thermostat failure can affect the mixtures and make car run rich when cold; hence the co...

The other bonus is that you managed to remove this pin with no effort at all, when it took a seasoned expert 5 or 6 minutes.

Perhaps that shop fitted some NGK Iridium spark plugs which it seems have a hit and miss success rate according to recent posts: https://www.matthewsvolvosite.com/forums/viewtopic.php?f=5&t=54863 Can you pull one of them to see? Would be interesting to see if they were properly gapped while you're i...

It could be one of them was faulty. Replacing them one at a time would have been a more accurate way of determining if it were the plug(s) I don't see what all the fuss is about plugs. If the fuse on a stick of dynamite is made of rope with some sulphur impregnated or a viscose fuse the resulting ba...

SRS module is the most likely suspect for me here. If the SRS LED light circuit in the DIM were faulty it would not light up. In this case the SRS module fails to detect the SRS light circuit and pulls up the code you see.

Glad it worked out.

A heads up on the company name would be great; not to shame them but as an indication of what to expect from them.
It's difficult enough to repair a car without so-called "experts" giving your parts a clean bill of health when they're in fact faulty.
