What sort of faults? Other than dodgy connections, what faults can
these presumably all-digital units develop? Or are there analogue/
power electronics in there that fail/drift out of spec?

Is now a good time to tell you that many recent ECU are conformance
coated or encapsulated so as to prevent "intellectual property theft"?
Therein rendering a car a writeoff with a diagnostic & replacement ECU
bill of 3500+?

Well it seems that some ECU's are coded to the car but then again the
firm I refer to seems to be coping very well with recent "electronic"
units and there are others doing the same thing.

I don't think that there're at all interested in IPT just getting the
hapless motorist back on the road at an affordable price;!..

Well if its like the PCB in our Suprima boiler its simple dry joint
problems with the odd resistor being of a too low rating but then again
an exchange one there has seen that working fine again:-)..

Just because its digital doesn't make it free from fault's all!..

I think the latter is likely to be the case.


I remember hiring a Ford once: halfway to where I was going te dashboard 
quit. I phoned up teh car hire, who told me to carry on. No speedo, no 
gauges, nada! I found an AA man parked by the road side and asked him 
..."bad earth on it, hit it with the heel of your 'and'"

Voila!.

crap car.

Good advice.

ECUs seem to be made to last, they have well built pcbs and are well 
conformally coated with plated through holes

The Suprima pcb, on the other hand ...

Volvo ABS ECU's from the 90's (late 850, early V70) were notorious for having dry joints.

Well.. We got as far as prising off the spring clips then decided that
we might damage it if we went further getting it open then we'd be in
the replacement game rather then repair. So all in all the charge for
repair wasn't that bad as we've spent sod all on parts for this
particular car anyway and we needed it back on the road so ..

But under any other circumstances I'd have had a go but I can't see your
average small time garage doing this sort of repair doubt they'd have a
soldering iron that small for a start;!..

But further articles indicate that there is a growing market for
electronic assembly replacements on cars which I suppose is simply
market driven by the demand and the silly prices for new manufacturer
replacements and the growing use of electronic assemblies. It seems for
instance that the firm I referred to spend as much time repairing
electronic dashboards as much else!...

I suppose.. It depends on what sort of faults there are?. Seems on the
unit I had done these might be simple dry joints but I wonder if there
are that many faults due to the multi layer PCB anyway?.

CONFORMAL coating has f**k all to do with preventing IP theft. It's
easily stripped to allow rework if you know the solvent to use.

Interesting.

My Audi currently has a problem with the Airbag ECU which leads to the 
airbag light being permanently on. We got it diagnosed and it turns out 
that it's a fairly well known fault: in cold temperatures the EEPROM in 
the unit can randomly flip bits and then it fails a checksum test when 
it tries to power on. Theoretically a re-flash would cure it.

The problem is I'd need to dismantle the entire centre console to get at 
it and then drive around with the car like that whilst it was being 
repaired:

Another common fault are the Infineon power control chips.
Only trouble is I've yet to find a source where I dont have to purchase 
several thousand at a time.

If anyone has any pointers to a source of Infineon chips in small 
quantities, please say so.

I once had a Motorola portable radio with a burn up on a 3 layer PCB. 
We were so desperate for the set that I drilled out a 10mm hole through 
the damage and with the aid of the exceedingly good track layout in the 
manual linked every track across the hole. It worked!! Trouble was it

That's the problem. Unless you have details of the PCB design, working it
out isn't cost effective for a one off.

Yeabut just how many times does that happen compared to the more usual
run of the mill faults?. Don't think I've ever had to do anything to a

I mention it because it has happened to me. On an aftermarket ECU I know
quite well. Offered to have a go at repairing one which had had a fairly
major fault at the ignition output and had burned some tracks on the board
- including an (some) inner one(s). Circuit diagram etc readily available.
But not the PC board design. It proved cheaper to rebuild it with a new
PCB, junking all low cost components.

I had a similar issue with the ABS on a 1995 850 T5 a few years back. I 
bought the security screwdriver to get into the ECU (about �3), took it 
apart, re-soldered everything and re-fitted. ABS cured, no further issues.

I think over time that the joints to the PCB-mounted solenoids that operate 
the hydraulic valves may crack and re-soldering sorts them out.

Anything that 'vibrates' or transmits some movement in any way which is
soldered direct to the PCB is a likely failure area with time. Hence
things like large transformers not usually being directly mounted. Where
they are - like TV LOPT - is a common place for failed solder joints.

Never a hard thing to do.

Especially with electrical.

Unfortunately not, it's been hooked up to VAG-COM and gives error 65535 
"Internal Control Module Memory Error".
