From the bench: BMW N55 DME, crank-no-start
The BMW N55 DME is notorious for Valvetronic actuator shorts that fry internal driver circuits — causing limp mode, misfires, BSD communication failures, and crank-no-start conditions. Many shops give up and quote an expensive dealer replacement. This Bosch MEVD17.x board arrived dead. We replaced the failed components, repaired the damaged traces, and reprogrammed it for plug-and-play installation. It's back on the road — at a fraction of dealer cost.
Mail-in module repair & replacement
How module repair works
Whether your module can be repaired or needs to be replaced, the process is the same — one work order, everything documented by email, and a working module shipped back to your door.
-
1
Submit a work order
Tell us your vehicle's year, make, and model, the module's part number, and the symptoms you're seeing. The more detail, the faster the turnaround.
-
2
Review & accept your quote
Our technicians reply by email with your options, exact pricing, and terms. You review and accept before anything ships — no surprises.
-
3
Ship your module to us
Send in your module. We repair it — or program your OEM remanufactured replacement — bench-test it, and ship it back ready to install.
Module faulty beyond repair? We'll program an OEM remanufactured replacement.
Not every module can — or should — be repaired. When yours is too far gone, the quickest way back on the road is an OEM remanufactured module that we program and match to your vehicle. Same work order, same quote-by-email process, often a faster turnaround than a repair.
It can also be the more economical choice — going straight to a programmed module skips the hourly bench testing and evaluation fees a repair diagnosis requires. You still send us your original module, and you get back a programmed, ready-to-go replacement.
A note on water damage
Water is the enemy of electronics. Once moisture gets inside a module, corrosion spreads beneath the components and the damage keeps progressing — which is why water-damaged units can't be reliably repaired. For these, a programmed OEM remanufactured module is the right fix, not a patch.
One form covers both repair and replacement — we'll recommend the right path in your quote.
✓ Upfront pricing
You approve the exact price and terms by email before any work begins. No hidden fees, no surprise charges.
✓ 6-month warranty
Every repair and programmed replacement is covered for six months against defects in parts and workmanship.
✓ 2-day shipping available
Expedited return shipping is available on request, so your vehicle spends less time off the road.
