Try to understand what they done to ECU

**hanswerner11** · 28th December, 2019, 11:14 AM

Hi everybody,

I bought a Volvo V50 2.0d (SID803A ECU). Seams that prev. owner made some changes to ecu.
EGR is blanked and no dpf on car. I got no check engines lights on dash, for almost nothing. Last week a water hose got a crack, there was no light in dash that water was realy empty! Thats an annoying "tuning".

I only got a Galetto 1260 clone (used it for my smart cdi) and a Vida Dice clone. I read hours over hours. I did not get a final vote if kess v2 (clone, red) works read/write via obd. I know a bdm100 would do the job, but I gave no skills in soldering, thats not a option.
I woulkd like to get a read and show your guys. As far as I know from my searchings, they maybe did this VOLTA thing!? My car still regenerates every few 200km and oel ist filling up with diesel.
Then decide to flash stock oem files and refit dpf and egr or better got a correct tuning.

Thanks in advance!

if i was you i would not try read this ecu with Galetto 1260 its garbage get kess v2 v5017 EU clone its cheap and more stable then china clone read it then post it here maybe used ECUsafe that deletes whole dtc table will probably need manual solution other problem you might run into is the obd plug from some volvos dont have a kline connection in them so might have to buy a separate cable to do them from alientech or use the kline wire supplied with the kess to probe the obd plug you can read up online on how to do this

regards

Thanks chrisimerk, will do so and report back soon

I think this ecu it can't be read by bdm only so kess is not enough....maybe ktag.

**chrisimerk** · 28th December, 2019, 07:52 PM

this ecu can be read by kess no problem if you have the volvo cable from alientech or use the kline wire suppled with the kess and probe the obd socket i done it numerous times

I'm stupid always take out the ecu...

yes it be a good idea to get a full read by bdm but if he doesn't have the know how on how to go about doing that then the easiest option is to read by obd as it is safe to do so if you probe the socket with kline as volvo dont have kline connection in socket and on these you can do dpf and egr off with just partial read

Even if there is a light that warns you about low water levels, that's not a function performed by the engine ecu, so that has got nothing to do with the "tuning".
It is your responsibility to check the water gauge if the engine is in normal operating temperature range and not getting too hot.

Thats wright of course, the gauge never got hot. But Reservoir tank was empty, guess in normal operations the car had show up a red light in dash. I think all error dash lights are just "disabled".

Best option would be too find the original file for the ECU for this vehicle and write back to the car, if you do try this report back and let us all know.

My Kess realy did arive this afernoon! That was pretty fast!
I was not allowed to do car stuff this afternoon of course.

I just got 30min...my wive is out of the house..

..just flip this thing to the obd port and did a read out...was a little scary...some lights flashed outside and inside, some dash warings and 3min later it says succeed!
I did not take one single breath in these two minutes!

Hope the file is correct, if not just let me know guys. Wish you alle the best for tonight!

edit: btw...this obd got a kline I thing, I did nothing special, just used the obd cable which came with the adapter *luckyme*

**chrisimerk** · 31st December, 2019, 07:56 PM

you got lucky some dont come with kline

**chrisimerk** · 31st December, 2019, 08:00 PM

just looked at the file they have wipped the dtc table

**chrisimerk** · 31st December, 2019, 08:37 PM

here you go mate flash this back on all cks ok after you have flashed it empty your water reservoir see if you get a warning light on dash

pass in pm
