Default ETM - Latest ETM & Volvo UK Info + Pricing/Contactless

The ETM has failed on one of my C70's.

In desperation I will be going to the old MRG Volvo site in Chippenham to get a new one fitted.

I was advised that Volvo UK no longer pay the labour the for this this work and that this good will gesture was terminated in 2006

PARTS COST

Replacement ETM
Gasket
Software

The above is costing me 234

LABOUR COSTS

This will vary from dealer to dealer depending on what their rates are but allow for 2 hours labour time.

In my case this will be 200 bringing my payable total for an ETM to 434! Not nice for something that could only last a very short time.

CONTACT REPAIRS

XEMODEX has been mentioned in another thread and I am considering this for the failed ETM which I will be keeping upon removal.

Also there are a number of contact-less sensors advertised on Ebay for around 75-80. Does anyone have any experiences with these?

My V70 is is the same situation (though not completely failed yet), so I will be following this thread closely.
Trying to work out the best option.
What kind of warranty do you get from the dealers, if any?

I am amazed I don't see any further responses to this thread. Like DSK, I had mine replaced in 2014 by an independent specialist in Wantage, Oxfordshire near me, who had to take it to Volvo to get the part and have it programmed. Total cost was very similar.
Five years and 49,000 miles further...guess what? Groundhog day!

I can't bear to part with the old girl; she's only done 188,000 miles and with the LPG conversion routinely returns the equivalent of almost 58mpg compared to the cost of petrol. I'm a retired electronics engineer so the mods required to fit a Sacer unit (the contactless device) are not a problem for me.
The parts are on eBay for 76, which is acceptable.
So has anyone else experience of doing it, or am I in uncharted waters? I doubt it.
Speak up chaps! Please?

If you can install a Sacer yourself this will save 80 but please be aware that these throttle bodies can fail for other reasons as mine did recently. A full Vida check is a wise first move to confirm it is indeed the position sensor fault.
Have look at my post, it's the one below this.

Well I do have a Vida unit, but I lost all the instructions so had to sort out again (all done now), so I ran the ETM test which came back fine (only 1.6 difference).
However, whilst running tests and familiarising myself with Vida, the problem re-appeared and I managed to graph it. Not sure if it helps, but screenshot attached. does Vida save this stuff somewhere so you can re-visit?

I also seem to have hundreds of fault codes recorded from all kinds of things that have happened in the past 5 years. Is it possible to see just the latest ones or should I clear down the lot so I can get a clearer picture?

What else could be causing the erratic running? I have ordered a new MAF sensor, as they are cheap enough, and will see if that makes a difference.

I suggest you clear all the codes and redo the diagnostic check and note the current codes. The Vida ETM test operates the throttle butterfly from closed to fully open 3 times and records the position sensor outputs but these will be almost identical if you already have Sacer fitted. The graph should show 3 similar parabolic shaped curves as the throttle opens and closes. I did mine with the ETM removed and visible as I did the test, in my case the throttle did not move during the test so I knew it was either the motor or the circuit board inside.
I would expect Vida to identify a Maf fault but I am not a Vida expert.
