did I understand you correctly that you have actually bought the "X" part on Ebay?

Reason I ask is that Ebay GSP shipping still seems to be functioning, perhaps a little slower than usual, and also I just received a Deutschepost/DHL item from Ebay Germany today. I don't have any experiences with Ebay out of USA in the last couple of weeks though

Sorry no, still on my original ecu. I know this sounds weird, but can you load a auto tune onto a chip?

Thanks for the reply's chaps. Im hoping to see the guy that did the job today. He is coming to my place to see if we can get it going. The chips came with the car and weren't fitted so i figured hey why not! I had him do my 850 T5 volvo first to check his work haha and that turned out fine. Seems to know a soldering iron from a blow torch.
Have tried to attach a pic of the chips,but the 'upload folder if full' Ill update you all with todays outcome if any.

Did your guy fit the socket(s) in the pics?

yes.

The work does not in all honesty look terribly flash. Did he do it all by hand with a conventional soldering iron?

I really don't know to be honest.

What is preventing you from reinstalling the original chips. now that sockets are fitted; did he destroy them when removing?  Sorry if I missed something here

Obviously a bad time for shipping due to the current virus but I think you have to cut your losses and source a known good ECU from a reputable seller, ie quattroforum rather than ebay.

Bad time for your vehicle to go down though. You may be lucky to get it going by the end of the year unless you can source an ECU locally.

Another way maybe to source some known good chips and try them. Maybe you can take your ECU to someone locally to swap chips?

Any resolution to this?

Just looking at the third photo you posted, looks like scratches in the PCB. This could be a cause of your dead ECU. Maybe an option to send your ECU to a PCB expert for inspection.

URS4 Avant

Hey all, thanks for your input on my ECU problem. No resolution has been found yet. Mostly because of covid 19, and a little because im feeling a bit down about the whole thing! So the car sits in the drive and haven't heard from the ecu chap. Waiting till level 2 before i get back into investigations!

80 Vert

You could try Anything Electronic in Nelson to look over it, have found them very good over the years.
The other is EFI tech / Car computers. Might be worth a call.

Blast, i saw you were wrecking that car and had some hope! Fair call you are selling complete. Im down but not out! Hopefully can resurrect what i already have. I have just seen a fair few s4/s6 cars go through trademe recently looking like they will be used as parts. Someone will have an ecu im sure. Also my 1st gear in the early 6spd box is getting a little noisy.. Not selling the g/box are you?

If you want to sell the noisy gearbox? I'd be interested for my S4

Nah the 6spd is still in the car, and with the ecu the way it is i imagine it has plenty of life left in it!

He piggy backed the ECU chips over the original? I don't remember reading that in the chip tune upgrade manual...

You cannot find "tunes from the net". You either have the chips or you don't...

There is no "automatic tune" that you can load onto your chips to make it magically repair itself.



You have two options.

1. buy a chipped ECU from quatrroforum.com classifieds. ($500 USA) Guaranteed good ECU.

2. send you ECU to an expert to determine if the tracers are broken or not. ($ XXX)

It just looks to be in a socket. Even OEM's in the 80's and 90's did this.

Socket is the right way to do it yes, sorry I was confused by his statement.

Other option is to buy some other chips to determine if the current chips are legit.

Have had the original chip fitted back to the ecu via the socket. Car is still no start. Originally the guy did piggy back the new chip onto the old original chip, this is what he did to my Volvo. On the volvo he put a switch which allows to switch from the original chip to the new chip and that works. But did not on the Audi. So then socketed the ECU for the after market chip, still no go. Soldered legs back onto the original chip and plugged them in and no go. Am sending to ALT Tune CHCH and Cody is going to send it to their specialist for testing. Will see what happens.
