Well second thing you can do is clean the egr valve and every pipe around there
Did you say to them about the fault you was having.
A friend of mine told me about the egr, after I clean the egr it was a big difference, when the engine was warm it wasn't even there.
I haven't taken it anywhere yet buddy. I'm going to try and eliminate the cause before I take it anywhere
Will a VAG COM diagnose the issue straight away?
Plug it in and look at boost while driving.
I've ordered a bluetooth OBD today to be delivered tomorrow so I'll get it hooked up and find out what's going on.
Let's hope I can identify the problem. I have noticed since changing the fuel filter its more responsive or is that placebo? Who knows?
Thanks again Davietdi
On another note I had a 55 plate LCR about 5 years ago and had a similar issue. It turned out to be the engine speed sensor. I was quoted £350 to fix and ended up getting the part myself from ECP for about £30 and got a mate to fit it for a few beers.
I guess this means I'm a cheapskate but I begrudge paying a fortune for simple work. Granted I'm no mechanic but I changed the fuel filter in about 5 minutes and got 35% off from ECP. I dread to think how much a mechanic would charge for 5 minutes of his time.
I've bought some EGR cleaner from halfords so will have a look at that tomorrow and hope it does the job...
Take out the maf sensor and drive the car around see how it acts, and look if it still smokes with the maf disconnected.
See to be honest know one here can really give the best opinion on what to do as we can’t see the fault in person. Log fuel boost and egr with vag com and look for something off
Hesitation is always going to be a restriction of fuel or air. So you can see that can be a number of thing in a car with egr turbo and the whole fuel system
It won't show up anything on vag com, take out the maf sensor see what it does.
So I have no fault codes. I've not taken it on a run yet with it plugged in. I honestly think my turbo is on its way out. At high speeds it makes a right racket. Like a whirring/mechanical sound
I ignored the hesitation becouse it was there only some times and after the engine warmed up It was gone, but after I rebuilt the turbo realised it was gone, mine was also making strange noises, I mean like a jet engine.
Just a quick update.... I have ordered a Mk3 Ibiza egr valve gasket (I've seen on this forum that it's helped with other people's issues) It's apparently a smaller diameter hole which restricts the amount of recirculated airflow into the engine.
I've also downloaded the torque pro app to go with my bluetooth OBD and not had chance yet to hook it up and have a look at what's going on with boost/MAF/Load etc. I'll post a graph once I get it set up and go on a good run.
I have noticed that the hesitation has not been as bad recently when accelerating but I still get the whine in a high gear which I reckon is the turbo is on it's way out
