Would you agree that there is an underlying issue that has caused the following to occur with 200 kms of each other.
1.Mosfet issue. Replacing mosfets caused other ecu issues so I replaced the mds80 with an mds81. All codes cleared up but misfire so replaced the coils. Engine perfect.
2 transmission started throwing errors and would go into limp mode. At the same time i started to see for the first time driving stability, dbc and flat tire system failure error messages.
3. Replaced transmission seals and tubes and fresh oil.
4. At the same time I Replaced rocker cover gasket and walnut blasted the valves. Put everything back together. Car starts and runs really smoothly. As soon as i get on the power i get 29dc and29f2 errors. Never seen them before. After restart i get the driving stability, dbc failure and tyre pressure warning failure errors again.
5. After one of the “breakdowns” the car struggled to crank (like flat battery). Left it for a few minutes and it started. Few breakdowns since, no starting issues.
I suspect an underlying wiring issue that is causing the codes? Why would my hpfp suddenly start having issues after a rocker cover gasket change ( which required rail removal)?
Help please.

Could be injector related or your HPFP

Any logs?

Make sure LPFP and HPFP are both logged as well as all fuel trims

Battery condition?
