Hi. Check the oil level, and if it is too high (overfull) then please take the car into a dealership. RegardsNeil

Have the system monitored with a special scan tool while this happens, that means a trip to the dealer. Buy a VW and experience unexpected acceleration!

vw has problems like this due to tranny fluid getting to low, when oil is low tranny starts doing crazy things, on your model im not to sure but most of the newwer vw's require a lift to check the tranny oil level. from under the the car theres a plug on the tranny pan, this is where you fill it and check it. there are a few steps like make sure the engine is at operating remp and on level ground an then you go through the gears and let it sit with engine runnig and remove the plug and some oil should leak out, that is full, its a tube inside the pan and when the pan is full it gets to the height of the tube and inturn runs down the tube and out from the plug you removed,the oil should just dribble out if it runs out steady then allow it to drain until the flow is very slow, this would be due to overfilling it. good day.

Go back to that VW dealer and complain. I'm sure you payed plenty, and I know in my shop, if a customer's car is not repaired to their satisfaction, I want to know, and make it right. Sometimes parts can be bad right out of the box, and sometimes problems are misdiagnosed. Go back, but don't agree to pay for anything untill you get a satisfactory explanation. Good luck.

as 2nd/3rd are the most used gears chances are the syncromesh on both these gears has gone,you need to strip g/box completly/or buy a recon box.

you dont say what miles the car has done.but you should now be using semi synthetic 20/50 oil and try using a fuel additive(redex/wynns)to clean the injectors.if you are using oil it is possible that the engine has lost some of its compression due to ring/valve wear.did you know that to convert your engine to a 130/150bhp unit,you only need to change the ecu try"diesel tuning"website.....

If the car turns over ok it is probably the EGR valve stuck... try moving it back a forth a couple times... i had the same problem...

hi if its just second to thrid then the clutch is slipping on thrid gear look at the boxes oil level is important but look at the colour is it red and tranperant as this is ok if its brown its a sign of the clutches slipping i would try a stall test on thrid gear first and if its ok second gear [manually] see is the engine stalls at the correct rpm if you thinkabout it imagine you are in thrid gear in a manuual box and suddenly drop into second it would be hard shifting it could also be a faulty thrid gear solenoid yates210456

The hunting and clicking is caused by a stuck vapor canister purge valve. The valve is on a vacume line. When it gets stuck open too much air enters the engine at idle or low rpm. This will cause the engine to hunt and stall as soon as any load is put on it if you do not rev it hard. The engine will over-run when coming to a stop and probably stall. It can come and go putting the chack light on. The quick fix is to just un-plug the solenoid. facing the enginebay it is located on the left hand side just infront of the suspention mount it is half balck half blue on every lupo i have seen. unpluging it will mean the car is driveable again but the check light does come on. It is 100% safe as long as nothing else happens that goes undetected because the light is already on. The part is about £70/80 from VW,  they may or may not know what you are talking about but i would not bother going to VW. The part is easy to find at a scrapyards if there are Lupos / Polos.  A number of other VAG cars share the part as well.  Any other problems come along to clublupo.co.uk
