VW Engine Management "Issues"

[Double Play]

Folks,

I’ve had a persistent engine light on my X reg (year 2000) VW Bora 2.0 for about a year. On a service today, I paid £25 to get the engine codes and they were reading was as follows:

(Earliest Fault) 17536 - Long Term Fuel Trim mult, Bank1 System too Lean

16518 – O2 Sensor Circ, Bank1 – Sensor 1 - No Activity Detected

16684 – Random/Multiple Cylinder Misfire Detected.

(Latest Fault) 16688 – Cylinder 4 Misfire Detected

Now the guy at the garage (not a VW dealer) told me that the 17536 could be the lambda sensor but the 16518 sensor 1 is the sensor before the cat and could lead to 17536.

However, I don’t want to get the sensor changed if it’s going to cost two arms and three legs and it’s not going to resolve the problem, as I generally don't like the whistle-through-the-teeth quote. As cynical as it may make me sound, it may lead to a train full of gravy for someone.

I’ve been told that sometimes a split in the air line to the engine could result in a lot of faults and all of the faults listed above could be the result (happened with a colleague's 1.8T Skoda).

Any ideas, anyone? I live on the South Side of Glasgow and if there’s a garage out there who won’t cost the earth to fix this, please let me know.

Cheers

if its a 2000, check the hoses, i found 2 split hoses last year after cleaning the engine bay with GT85 and a rag, not visible unless you run over them. Amazing how gunked up these get over time, an internal clean can help.

Your issues are on an NA engine, the 1.8T and 1.9TDi are knowned for MAF issues. 1.8T of the early 00's known for coil packs failing. But on an NA 2.0 lump a sensor sonds more likely. Havbe a look in the recommended garages list in the Scotland section of the forums. Would find a good indy VAG garage.
