So I cleaned my cruise control radar on the weekend and now my cruise works perfectly again. Let my car idle for 5 minutes after a big drive when i got home, . Go to turn it off and the check engine light is on, I thought it would just be the brake pedal sensor, took for a spin with the brake pedal switch "off" and it still didn't clear. So this morning I checked the codes and I get 0235 and 0171

0235 Turbocharger Boost Sensor A Circuit Malfunction

0171 System too Lean (Bank 1)

Anyway I am pretty Stoked :no: , thinking maybe boost solenoid is caput? anyone else ever had a fauly like this? Please help if you can

Also at idle I get a very little miss I can hear and just see on the tacho, so going to do plugs etc aswell...............

So crisis is over, took of the engine cover to find this......post-41430-0-08414200-1321232071_thumb.jpg...thank F*%K.....put pipe back on, cleared code drove around the block, idle is sweet and no check engine light .....please delete thread mods

Mmm, fuel regulator reference hose will definitely make it run lean. I eventually put cable ties around mine to stop this happening. Why did this make the boost sensor come up though?

yeah I just ziptied them too, dont have a clue about the boost sensor though, I am just running evrything stock (no boost controller etc)

Maybe because a decent amount of boost would bleed out of that pipe....?

No, not much, its only a 2.5mm hole. Perhaps it throws a code if theres not enough vac but I doubt it.

Just another M35 mystery then :unsure: .

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
