Can anyone offer any possible suggestions to my problem? I do apologise if this issue has already been discussed elsewhere.

My car is currently putting out 215bhp but is down on torque as is only running 260ft-lbs. These figures were taken from Awesome's Rolling Road. It is running a Turbo Dynamics stage 2 hybrid along with a forge front mounted intercooler and straight through exhaust system. The map was taken from a similar car with the same turbo, this car made 215bhp but 310 ft-lbs of torque! Unfortunately Awesome didn't have time to investigate the problem. My thought may have been down to the MAF sensor. Would this be a good place to start? I have ran the car briefly without the MAF sensor attached and things felt pretty similar, it certainly wasn't any quicker. It is quite difficult to tell as the car is still fairly fast when it's down on power.

Any ideas will be greatfully received.

Well, are you sure it is even 215bhp? BHP and Torque are correleated so it is rare for two similar cars to have a different ratio of BHP to torque.

are you saying you took the ecu off another car or have copied the map? what was the other car it could be something to do with it.

If you disconnect the MAF and the engine runs the same that could indicate a problem with your MAF. Try a new one. Mine was 100k miles old and ran oiled air filters which could contaminate the MAF. Not sure if it will bring back your ftlbs but your engine will run much better.

Incidentally my pd 130 made 191bhp and 360 ftlbs on the Awesome dyno on a 25degree day. It made 205bhp 380ftlbs on jabasports dyno on a 4 degree day.

Well, are you sure it is even 215bhp? BHP and Torque are correleated so it is rare for two similar cars to have a different ratio of BHP to torque.

they are linked, but only if you know engine speed? it could be that the OP is missing the usual low-down torque spike, lag because the VNT it not set up properly? without knowing how it drives or seeing what the torque/power and boost graphs are like who's to know what might be the cause??

Was that max torque? If so the figures don't add up, power bhp = (rpm x torque (LBs/ft)) / 5252

Peak Torque is normally 1900 -2200 RPM and Peak BHP 3750 - 4000 RPM, but depends how its been tuned

To follow on from Bondi, assuming peak power was at around 4000rpm then 265x4000/5252=201bhp

Have you got or access to vcds? If so logs in 3rd or 4th gear from around 1500rpm to 4500rpm will help to see if theirs a problem.

devonutopia – Yes, definitely 100%, 215bhp and 260ft-lbs of torque. It’s made 215bhp on 2 different rolling roads.

joe_vrs_tdi – Joe, I took my car in for a new clutch and flywheel along with a custom re-map. The clutch was done and the car put on the rollers. They ran the car to see what is was running and were a little confused as the car made 215bhp but 267ft-lbs. To rule out the mapping they took a map used on a similar vehicle running an identical turbo to mine. With this new map it made the same bhp but slightly less torque at 260 ft-lbs. So in short it was copied from another vehicle. They put my old may back on and off I went back to Swansea

mr rooney – I think I’ll try a new MAF sensor from Skoda anyway just to rule this out. Would be worth a try. The one on the car at the mo has done 90k so is probably a little tired anyway.

This peak torque was rather high up the rev band and close to the 3500rpm mark I think. This was how the car was originally mapped as I’d asked for more power higher up the rev-band to preserve my clutch a little. I presumed the torque was limited some-what as it was originally running the standard clutch hence wanting power after the 2000rpm mark. Upon reflection this underlying problem might have been there all along. I do remember the original mapper (not your man at Awesome) saying something about reaching the limit of the MAF sensor. I know these sensors when working properly should allow the car to reach way over the figures mine is pushing. So this is another reason to suspect the MAF. He didn’t say anything more about that and I’d forgotten all about it. Now I have my uprated clutch I wanted to bring the torque right up.

I don’t have access to vcds unfortunately. Might be worth finding somewhere I can have the car checked for any fault codes. I’ve had enough of garages charging you to scan your car only to tell you there’s nothing showing as being wrong with it! Very annoying. I may look into buying VCDS as would be worth while in the long run. But I cant afford to do that right away.

Ohh the other issue which might be relevant is I’ve twice tried to have garages remove the warning light (the one that stays on after you first remove the EGR Valve). This has been unsuccessful as the light has come back on. I do believe this is also the light that would indicate a MAF sensor issue, is that correct?

Many thanks to all

You really could do with carrying out some logs. Maybe look to see if any members in your area have vcds.

Without seeing what's happening it's just guess work.

Is your engine the ASZ or BLT? ASZ theirs a switch inside the map to turn off the EGR. Not looked at the BLT.

Didn't awesome offer to troubleshoot seeing you went all that way? Shame I'm not too far from them. Could of taken a look.

Dont get me started on Awesome! This was a 500 mile round trip. I arrived at 8.45am and the car was taken it. It wasn't until around 4.00pm and the car was lowered and the installation of the new clutch and flywheel was complete. Just after 4.00 the car was put on the rollers. Then about 5.30 they came and told me there was an underlying fault with the car and they didn't have time to investigate it. They also didn't have a clue as to what could cause such a problem. So yes I went away very happy that I've travelled all that way to what I was told are a great company to use. I was there the whole of 9hrs in their waiting room and not once did anyone come and give me an update with what was happening. Gonna leave it at that!

The engine in mine has the ASZ code. I am able to try (before I buy) a new MAF sensor so shall give this a go out of curiosity first. Failing that I will be on the hunt for some one/garage with vcds to check it that way. If it makes any difference I have an EGR delete pipe fitted but have been unsuccessful at getting the dash warning light to stay off.

should of just went to got boost in bridgend.

That's who's tuned it previously. I've been there twice now and both times the torque has been the wrong side of 300ft-lbs. In Got Boost's defence I was running a standard clutch, thus needing to keep the torque down. The second trip I did ask for it to be pushed and if the clutch did go I'd go and replace it. So yeah I believed he was being conservative as to not destroy the clutch. It would appear there is an underlying problem somewhere and they were unaware of it and didn't bring anything to my attention. As mentioned the only thing I can remember was a confused look on his face and he though he'd hit the limit on the MAF sensor. Still baffled.

I could guess at a boost leak or turbo vanes too open or stuck open but they're just guesses.

Though the other thing that makes PD TDIs go more "petrolly" is the camshaft timing. Can have a great effect on the way the car drives and the fuel economy.

Probably best to get the car logged or get VAGCOM and log it yourself.

You have plenty of room with the standard MAF sensor. Limit shown in vcds is 1249mg/str but I believe this isn't the sensor limit. This diagnostic limit can be reached with a standard turbo but it does drop to around 1000 at 4k. Hybrids should still be reading around 1200 at 4k.

If its reading low then yes it's a MAF sensor fault.

Thanks guys. Will try the MAF sensor first. If that doesn't work I will get the car read for fault codes. If Still nothing then I'll be looking at a pressure test on the boost hoses and cleaning out the turbo vanes,

Thanks

Jack your not the only one mate. Awesome GTI are full of ****, you waited 9 hours but atleast your tubro's working right. I waited 2 weeks and £1300 short, now i have a unknown turbo lag problem and the car is way slower then it went in. They fitted a faulty turbo, robbed my money and now dont want anything to do with me. Nice customer service Awesome. People on this forum should understand they are not as professional and credible as they seem. Yeah maybe for parts they might be on the spot, but when it come to troubleshooting and ruining customer cars Awesome GTI come first. I rather let a bunch of monkeys work on my car, they'd do a better job. There figures are highly inflated! I wouldnt use them ever again. Im pursuing legal action against them, they dont deserve to be on these VAG forums.

Would be interesting to hear awesomes view on this.

Final question could this be caused by a faulty throttle position sensor? I did read some where this can cause a loss of torque but you still make max bhp. Unsure if this is the case. The car does rev at idle which could mean a faulty TPS. However I cured this using a bungee cord to apply a little pull back on the pedal instead of using my toe each time. Is it possible this could be it? Thanks

VCDS can be used to show throttle position %age so another thing to check mate

Yeah I am gonna have to bite the bullet and have it checked. Just called Skoda who wanted £96 to plug the car in! Ouch!!!

It's worth investing in your own. Will save in the long run.

I could help out probably mate, I'm no expert with vcds but could do some logs with you some time if others tell us what channels need to be logged etc

I can supply you wish a list of groups to log.

Have you got or access to vcds? If so logs in 3rd or 4th gear from around 1500rpm to 4500rpm will help to see if theirs a problem.

Post the results and I'll tell you what's what.
