Golf 4Motion - lack of power at low revs

[whodeman]

Any chance anyone has had a similar problem?

The car has been into my local garage a couple of times in an attempt to get it sorted but to no avail. Had the MAF sensor changed, and the Temperature sensor too for an unrelated fault.

The car drives fine, pretty much spot on once you get the revs up. But it takes a few seconds for the power to kick in at low revs - almost like a turbo lag.

Any help would be greatly appreciated!

have you had the fault codes read? It could be a sensor gone, maybe an o2 sensor. Or camshaft sensor? Not an expert but i did have a similar problem on a 5 series and it was both the above sensors.

[whodeman]

Yes, had the fault codes read - temperature sensor and camshaft sensor both reported faults.

Had the temperature sensor replaced, but left the Camshaft sensor as it was reading fine when in the garage.

How does that affect the power?

Well, if the motor has variable valve timing then I suspect that the cam sensor is the input to the ECU that controls the valve timing. That is going to affect the power curve somehere.

anyone think it could be something simpler (cheaper) like filters or plugs?

[phumy]

Oh go on then, i'll say it. It could be plugs and filters.....

Make you feel better? But then it could be something else

Oh that's right, pick on the new kid why don't you!

I think they're like that at standard!

Gearing isn't the best apparently.

I hear what you're saying about the gearing - it won't get to 60mph in second gear.

But this is a recent problem, something which has just begun to happen. The power was fine when i bought it - instant when you hit the pedal?

But you asked for it, didnt you?

This has descended into chaos!!

op, If the garage cleared the codes, go get them read again, if the camshaft sensor is kaput, then there will be a new code for it.
simples!

Camshaft sensor isn't bank busting.

If that is what is bringing up the code then I'd go with that.

[whodeman]

Thank you to you all, I'll get the Camshaft sensor changed, hopefully it'lll solve the problem. I'll post the 'result'...........

cheers

Read the codes first!

He did.

Came back with temperature and camshaft sensor faults.
