A4 B6 2.5TDi Q Remap Help

I am now looking at a remap to resolve the lack of power under 1800 RPM the 2.5TDi suffers and also to get more power from the motor.

My car has the auto/tiptronic box and I'm told this affects which remap I can get.

So which remap company/product is best. Cost isn't an issue, just getting a better running car is important and reliability in the long run......I don't want to engine blowing up in 12 months just cos I had a remap.

Thanks
John

Yes it is.

Hi Rich,

Your Mrs was singing their priases on Saturday. The price is quite high considering they don't offer rolling road tests for before and after and they also only show a 20BHP increase where as others seem to offer 35BHP and at the very least a good amount of driving around to test the remap once done.

My only other concern is only AMD seem to mention that my tiptronic gearbox will need to be reampped too. So I now don't know if I should go with AMD or if the gearbox ECU can be left alone.

So many options and so confusing.

John

DPM (sorry I didn't get your name on the phone before),

Thanks for the update on the gearbox ECU. I take it this is included in the price you mentioned on the phone? Any movement on that price for being a member on here??????

I have the Auto box, tiptronic, as I have Quattro and for some reason it doesn't go with the multitronic gearbox.

I have got prices on tune-it bolt on box and remap but prices start at £500 and go upwards to around £750 for a remap.

Maybe we could see if someone would offer us a deal on the 2 cars being done at the same time?

That sounds quite good as they come to your car and the price is more reasonable too.

Ask them how much if we both get to one place and they come to us?

John

Paul,

I just sent you a PM.

thier website says £300 per car, http://www.celtictuning.co.uk/prices.html

Maybe worht asking them toconfirm thier prices again.

John

DOH, silly me missed that bit.

Well, Pete, from Celtic Tuning has just left. Arrived at 7pm and 2.5 hours later we went on a nice 140mph test drive.....which more than pleased Pete.

Over about 20 minutes drive around A, B and M roads the power seems stronger from any point you floor it. I'll be out in the Cheshire plains tomorrow so will report back more then.

John

Well I'm now really miffed.

I spent all day yesterday driving around in my car and wasn't impressed at all with the new remap.

I either had way too much power with just a slight touch of the pedal or drop outs when accelerating.

The tiptronic gearbox also was now having a problem deciding when to change gear and sometimes changing down or up a gear ever other second. At one point the gearbox wouldn't select any gears at all and ofter waiting 40 mins the nice RAC man came and said the car was in limp home mode and after a quick play on his laptop, whilst connected to my car, he sorted that out and I was on my way again.

I called Celtic and mentioned the problems. I was told Pete would be back to look at my car. This was better than I was expecting and was then happy to wait for a couple of hours to get this fixed.

Pete turned up and checked the car over with VAG Com and find no real faults. He then had another version of the mapping and did remap V2. We went out for a good drive round and whilst the fierceness of the power had gone the gearbox problems had not.

He called back to his office and a chap called Dave who was in Ireland then said he would try again with remap v3. It transpires that Dave has extactly the same car as me and is clueless as to what is causing the problems with my car.

Some time later we had remap V3 loaded and went out for a drive. Yes, you guessed it, the gerabox problems were even worse. I also noticed the power gain had almost gone and it drove with the same power now as it did prior to any remap.

Pete then laoded my original mapping that he had taken off my car on Tuesday. We then went out for a drive and my car was now back to it's smooth gearbox self, with the same power as V2 and V3 of the remap.

So remap V1 was mad power and I really mean mad, as you pulled your foot off the power the car accelerated more until you pulled your foot righ off the pedal, very fierce gear changes, around 40% lower fuel consumption and just a really wild mad driving experience. It felt like I was driving a manual A3 3.2 quattro I was once given as a service car, just manic power that was either on or off.

So I am now back to the standard mapping on my motor and have been driving around today very content with my smooth power delivery and smooth gear changes. I almost feel the £350 remap isn't worth the gains, gearbox problems aside, as the extra power only fills small gaps in the acceleration of the normal mapping and top end speed is no change. you get far more to the gallon and unless you drive "on the limits" the extra power gains are just not worth the money.

I hope this has been a good insight into the, semmingly, mine field of problems you might have when having yoru car remapped.

On as secondary note nearly every chip or remap place I called all said that my car either did or didn't need a seperate gearbox mapping loaded so it seems no one really knows how to solve the gearbox problem. Another strange thing is when aksing for rolling road tests for my car no one would guarantee my car would work on the RR as the gearbox is neither full auto nor is it full manual and it cannot be set to hold in each gear for the power to be tested.

All I would say it if you have anything other than a manual car you might want to get someone to try the remap on yoru motor before you pay and if you are trying to RR your auto car then make sure you try a place who has already correctly tested your type of car on the RR.

John

I am back to the original setup. I have left messages with Celtic to ask what they are doing about the problem but they have not returned my calls.

I have decided I wouldn't let them work on my car again but it's your decision and it may be a different story on your car.
