Yes you got ripped off yesterday you can drive away to any place of repair so best complain to dvsa report the testing garage for profiteering I'm sure the local agency guy would love an opportunity to big him self up.

It's 2025 I mite just mite part with my L322 iv got my eye on.....an L322 supercharged ;)

That's good news they have both been changed the aur tank usually leaks at the front causing the pump to run constantly until it finally fails. Still worth checking for leaks with the soapy water spray.

Weak pump and or a leak in the air tank both very common on the d3 and d4. Checking gallery pressure eith diag can help locate a fault if you indeed have one.

Keep dreaming go ask the insurance companies.

I have a how to guide on here

It's pretty simple on the m62 to be honest no nasty surprises. Just go to local motor factors and stick with their premium brand NOT ****part and get your self a spare gasket just incase.

If you didn't tell your car you fitted a new battery then it's most likley over charged and cooked it. The D4 has to be tolled a new battery has been fitted due to intelligent charging from the alternator.

Mot passed this week but did find an oil leaky which turned out to be from a damaged engine oil cooler fitted in front of the os frontcwheel with a silly bit of plastic to protect it :vb-groan2: Removed and repaired by local specialist as seen on wheeler dealers when it was good with the China.
