Any possibilities for changing the n55's from Continental to BOSCH?
Hey guys, I have a E92 335i(N55&DCT) manufactured in 10/2010.
And we all know that 335i has two HPFP(high pressure fuel pump) corresponding to the Production Date before and after 2012/04- Continental and BOSCH. Many people experienced the HPFP failure. So is there any possibilities for changing the n55's from Continental to BOSCH? We know the differenec from Continental and BOSCH are vacuum pump, HPFP, Speed sensor(Installed on vacuum pump),DME and some other kits. The early DME is MEVD172 and other is MEVD1726. By checking ISTA, I found that early DME(MEVD172) also had pins for the HPFP speed sensor and they were in the same position. At least that's what the circuit diagram I looked up on ISTA told me. Now i've install all Bosch HPFP KIT, but still dont konw whice ZB number is for 335I MEVD1726. So can I install a Bosch HPFP KIT and connect the sensor to the DME(MEVD172), while flashing the MEVD1726 program using Winkfpt to run my 335i? I suspect there is a high probability that I can only solve this problem by switching to a later computer version, but I am still willing to try various methods. |
