Vw mkv r32 too lean codes.?
I have a 2008 vw mk5 golf r32. It threw four codes last week. Banks 1,2,3,4 too lean fuel trim. On very hot days this results in what feels like fuel cut outs. 2-3 seconds, and gets progressively worse if you keep going without cooling off. I replaced the mass airflow and it cleared two of the codes. The shop checked all vacuum lines and could not find a leak. So we replaced the fuel filter. The codes came back the next day. I drove for a week with the codes on and nothing odd about the cars behavior. Today nice and hot in the city the fuel cuts returned. At this point I am tiered of throwing money at it. The only things left I can think of are fuel pump or a sensor seeing too much air. I don't know if there is something else that could be responsible for this. Any ideas? I don't know if this car had the fuel tank recall done or not, I can not find a sticker indicating it has been done.

The problem is you and your piir oil choices. AUDI / VW require Only oil with the spec.numbers 502/505 on the oil labels. RAVENOL is Audi official oil good for TWO FULL YEARS. Other ouks are Total Energy oil from France MOBIL ONE 0W-40 oil, Pennzoil Ultra Euro with 500k mile warranty, Am soil and a few others THE USE IF VALVOLINE ewcost you DEARLY in expensive engine parts replacements as turbo feed pipes fill with tar and sludge and coke bake into oil spray jets and chain yensioners. These codes tell you that your air fuel mixture is going off kilter and that your converted may be overheating. <<<<<take $20-50 to ant oil change place and have the throttle body and the idle air control valve cleaned to SHIWROIM FACTORY clean. Get a motor much and use ONLY Audi approved oils. Your fuel mixture will improve afterwards. BAD OIL CHOICES RUIN AUDI CARS. TAR bakes into sensors and engine metals and will NOT her removed without engine cleaner chemicals. Use BLAUPARTS for tools and Audi we
Source(s): Wear Items and RAVENOL oil and fluids. Until you get oil cleaned out and IAC valve restored you will get trouble codes. PENNZOIL ULTRA EURO gives a 500k mile oil warranty. MOBIL ONE 0W-40 is the easiest REAL oil to find. Use rgmudje@yahoo for all VW AUDI questions. I SAVE THEM from doom. Bye now. - Anonymous7 years ago
Have the dealer do a smoke test for any vacuum/intake manifold leaks. Dont suspect a fuel pump unless all four cylinders are running lean
