Question about 2002 Audi A4

1 Answer

1.8T with cold start problem.

I have a 2002 Audi A4 1.8T, my problem is sometimes when I start it the car will not go into high rpm (1200 RPM), instead it just stays at 750~800 or something. This happens only in freezing temperatures, and for a second or two will run really rough and then everything is fine. As I said this happens only when the car is cold and when outside temperature is on the freezing mark.
I am thinking this might be cold start sensor but I don't even know where it is nor how to find it.

Anyone had similar problems?
Thanks

The engine temp sensor is located at the back of the engine above the gearbox. It is usually green with 4 wires if there is only one sensor, or 2 wires if there are 2 seperate sensors. make sure engine is cold, remove plug, then slide clip out and pull sensor free.

What is the factory Idle rpm for 22re efi engine


I've seen from 500 to 1500 RPM in all the manuals I've been through, depending on the year and application (truck/car). In personal experience, 650-800 RPM is acceptable warm operation range. This will also depend on elevation. Will go up to 1200-1500 RPM for cold starting. I live at about 2000ft and my '86 Pickup 22RE idles at 725-750 like a top after about a 3-4 min warm up @ 1250 RPM if it's cold (<45ish).

The check engine light on a 2001 beetle read code PO118 engine coolant temperature circuit high input. what do i do?


16502/P0118/000280 From Ross-Tech Wiki Jump to: navigation, search Contents [hide] if (window.showTocToggle) { var tocShowText = "show"; var tocHideText = "hide"; showTocToggle(); } 16502/P0118/000280 - Engine Coolant Temperature Sensor (G62): Signal too High Possible Symptoms
  • Difficulties with starting a cold engine.
  • Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
  • RPM at idle is irregular.
  • With all engine temperatures idle rpm will often vary between 900 - 1000 rpm.
  • With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
  • Bad acceleration during warm-up.
  • Diesel Engines: Glow plug indicator may be on for a longer than normal time or at ambient temperatures where it shouldn't come on at all.
Possible Causes
  • The electrical signal coming from G62 is too low
  • Wiring and/or connections faulty (short circuit?)
  • Engine Coolant Temperature Sensor (G62) faulty
Possible Solutions
  • Check wiring and connections
  • Check / Replace Engine Coolant Temperature Sensor (G62)
Special Notes
  • In many cars between MY 1995-2002 the G2/G62 had a bad reputation for failing often. The original G2/G62 sensor is black and the improved replacements are green.

When started idels high about 2000 rpm then drops when hot cold ?


the iac probably has carbon built up around it this controls the idle speed try cleaning it first,if not it could be a bad iac or a vaccum leak that the iac takes some time to compensate for to control idle.

My Audi 97 A4 revs high when i start it and then .transmission pulls when changing


I have a 99 a4 and it revs to about 1200 at first start, after a minute or so it lowers to about 750 rpm which is the norm.It has done this since it was bought. Also when the air condenser/conditioner is on it idles high. The condenser is run off the engine so i also lose a few horsepower.

I'm not sure what "transmission pulls when changing" means though, needs clarification.

2002 Audi A4 Esp Light comes on, car turns off when I have to sto


I had the same issue with my '05 A4 1.8T.  Turns out it was the RPM sensor.  Audi tried to tell me it was teh fuel pump and the cam-shaft positioning sensor.  Paid for teh fuel pump replacement and it died 6 blocks from the dealership.  Then they replaced the RPM snesor, works great now... Except it's still an Audi.
