just got my self a 2002 octavia vrs 2 weeks and having a few problems with it.

the asr light keeps coming on randomly ?

the engine when running is dipping in revs just on tick over and when driving it if u put you foot down u get abit of a jerk before it picks up?

i have tryed scaning with vag com but its not reading that well i only have the free version but it has brought up some codes any help would be great!

If you can get some codes then check the VAG-Com section on this site or the Ross-Tech site and find out what the codes are indicating.

A randomly flashing ASR light can be a sign that your MAF (Mass Air Flow) sensor is on it's way out. It's located between the airbox and turbo. You can try unplugging it in which case the car runs on default MAF values.

If unplugging the multiplug to the MAF makes the car run better then its definately your MAF needs cleaning or replacing.

I have a 2004 vrs and I have been having the asr/abs light intermittently, when I managed to get it plugged into vag.com it came back as being drivers side front abs sensor. From doing some reading that one seems most common to go wrong and it may be worth giving it a clean which I intend to do today now I'm off work.

You really need to get somebody off here to plug it into a full vag.com.

As for the hesitation, has it been serviced regularly? No experience myself but from reading cleaning the throttle body and checking the usual stuff like condition of the air filter and spark plugs seems a good suggestion. If it is on its original ignition coils it could be worth changing those.

My asr some times lights up, I think its down the the crappy Nexus tyres the previous owner put on the front wheels. Get it hooked up to VAG comm mate.

hi , the dip in revs could very well be the Air Intake Temp Sensor in the Throttle Body . I had this problem when the engine was cold and would stall 95% of the time , but on the odd time did it when it was warm . I only found this out when the car went into skoda .

The traction control light could well be the MAF sensor i also have had a new one of these to due to my car being hesitation . we un-pluged the MAF sensor and it turned the traction control light on so the problems your having maybe interlinked to what ive said .

i have put a new MAF on, and a temp sender because the temp gauge kept dropping down.

have got some codes on my laptop at home so will have a look on.

wasnt sure if it was an air leak somewhere causing it from reading other peoples posts on here?

A common problem for revs dropping and ASR light coming on is a air leak in one of the hose's at the front of the engine underneath the front plastic cover and metal bracket. You may be able to hear it.

This will throw a fault code too. My friend had this recently after first replacing the MAF which did not fix the issue.
