'93 Eurovan needs an ECU
So I brought my EV weekender (5-speed) into a reputable shop to get the clutch replaced
and they did a fine job. Although 10 days later it died on me. I towed back to the shop and they say it's the ECU. I found another ECU at a salvage yard and although I couldn't read the O/E numbers - it came from another 5-speed EV so I purchased it and brought it in. The shop said it was bad - so now I need to find a new one. The folks at SIA would rebuild mine for $300. Does anyone have any suggestions? __ Matthew in Boring, OR |

Two bad ECUs in a row? Find another shop that understands diagnostics.

Did they have the vag-com or equipment to enter in your VIN info? If not that could be a/the issue. Also, I have a '95 5 speed & one shop told me that it needed a new ECU. It turned out that the vaccum line from the ecu was accidentally pinched (by the shop) when they replaced the plastic cover on the ecu. Once the vacuum line was correctly routed under the plastic cover it ran fine. Good luck.

Hi Jim,
What have they done to test the ECU? There are a number of things that can go wrong. I had a bunch of trouble with my ignition and after many hours and rounds of testing I think the problem was bad grounds, which caused the ECM to fail (twice, actually). Have them double check the vacuum hose connection to the ECU and the ECU wiring, in particular the grounds. One of the grounds in the ECU wiring harness is to the engine block, could it have been detached when they did the clutch and not put back? This is wire #29, Brown with black stripe. There are 2 other grounds as well. There's a document in the files section of the EV_update yahoogroup on testing the ignition in 93 EV's. Go through these tests and see if you find a "smoking gun". Check for trigger signal in the low voltage wires to the coil, if there is a signal there the ECM should be OK. The coil is a common failure point in these EV's, according to the list. If you do a search for stuff posted by "imothers_2000" you'll find a bunch of questions and answers going back almost a year on this... the first breakdown was just about a year ago now. $300 for a rebuild is a good price. The only place I found who seemed like they could rebuild mine wanted $500. Be cautious with rebuilders - ask questions. I found out that many can't handle the German stuff, they focus on US and Japanese units. It all sounded good on the phone until I asked a few detailed questions. Drop me a note if you need more info, I have more experience in this area than I ever wanted!

It goes from the nipple on the inside of the cover to a bellows mounted on the circuit board. That piece was bad on my 93 EV and caused it to run poorly and generate a code but did not totally stop it from running. Joe R |
