My cars been great this summer up until a few weeks ago when I lost boost (from 7-8psi down to 0-1psi) and feel like I have no power or turbo at all, so I ran a vagcom check and out came these fault codes in the picture I've linked. I have no idea what they are? Maybe someone could help me please?
I'm just wondering, but my friend linked up his vagtacho to my car around the same time and it sent the immo nuts. Had to use vagcom to get the immo to behave again. Could this have anything to do with it, or is this just a coincidence? I have a feeling he did something with the eeprom maybe?
I've checked around the engine compartment for signs of leakage all around the air hoses (turbo, air filter/maf and intercooler hoses) and pressure/boost pipes (intake manifold, turbo and gauge lines) and also the fuel line and pump but couldn't see any obvious leakage. Everything seems ok. Is there any others or anything else I could look for?
Could the boost problem be something to do with the DV, wastegate or exhaust?
