Good morning guys, we have an 06 BRM with 265k. This post will be long-ish, so get strapped in as we recount the timeline 🤦‍♂️

May of 2024, a very concerning sound started happening in the 5spd gear box. It sounded like it was about to grenade. So, we pulled the engine and transmission to do a full refresh. While the motor was out, it got a new rear main (has crank sensor on it), full timing kit, and replaced the vc gasket. While the engine was out, we taped off all the orifices and pressure washed it down over the summer. Surprisingly, it was converted to smf, but to replace the pressure plate and disc was more than putting the dmf back in. Also sourced a replacement 5spd from a donor car that was wrecked.

A few days ago now, we got it all back together and finally got it to crank last night. That’s all it did was crank (didn’t act like it wanted to start). After about 10 seconds on key, the oil light would start flashing, and it set the p0341 code. Now when we did the timing, it’s got the continental belt, hepu wp, and schaeffler tensioner and idler. We didn’t pull the cam pulley off. The 3 bolts were loosened to get the belt in, set the tensioner and it put the 3 bolts back in the center of the cam pulley where by eyeball it was before, and the the motor was rotated 2x at first, easy slide in with the special tools, didnt like where the tensioner pointer was, so set the tools again and readjusted the tensioner. Turned it over again 2x and the tools slide in easy.

We haven’t verified the timing yet other than pulling the top cover. We did unplug the cam sensor, and the ecu changed to cam signal missing. So, it seems the cam sensor is working. Do ya’ll think were on the right track with timing? We don’t have vcds unfortunately just yet so checking the torsion values isn’t going to happen anytime soon. If timing is correct, start checking for voltages, resistance and continuity yeah? Thank you all in advance for your thoughts. This is our first tdi, and needless to say, we want her to last for a good long while :)

Have you primed the fuel system with VCDS? I think it’s group 035 or 036. That will run the intank pump for 30sec instead of 2sec. Then hold the “gas” pedal down a little during cranking.

Sorry just re-read and see you don’t have VCDS. You can cycle the Key a lot to slowly prime the pump or pull the back seat and “ hot-wire “ the pump to run continuously during cranking. Another option is applying a vacuum on the tandem pump to suck fuel into the pump and head.

As far as timing goes you could recheck it by just re-installing the timing lock tools. The three bolts on the cam gear should be about in the center of the slots.

I did hold the throttle open while cranking .. I also opened the bleeder on the fuel filter canister several times. The bolts are center slots, so that’s where I’m thrown off. I’ll see if I can get to the car today and get some photos.

What if the cam timing to too far out? Since you loosened the cam sprocket bolts. Did they go back to the exact same location?

Yeah I was happy to see the timing was dead nuts accurate from where it was prior. So, we have verified on the cam sensor pins 1 to 3 there is 5v. I think pin 2 showed 5v too, but I don’t recall as it’s been a few three days 🤦‍♂️ we're waiting for new oil to show up before going much further. Is it possible the cam sensor could’ve died while sitting ??
