Often times this is found with the one or more of the following codes: 00576 - Terminal 15: Electrical Fault in Circuit. 00884 - Ignition Switch (D) Terminal X : Electrical Fault in Circuit. 01744 - Ignition Switch Terminal P (D) : Electrical Fault in Circuit. The most common cause for this is the Ignition Switch (Electrical Portion). 1.9 8v TDI PD150 ARL Engine (Current Figures: That way i can have full boost very quick. Turbine size isn´t telling much for spooling really, in fact bigger I would love to build a mild modded tdi, just to have something a little off the beaten path, but if it's not realistic compared to a 1.8t 20v, then so be it. I've owned about a dozen vw's (My current Type 3 Squareback on air, 5 mk2 roccos, mk1 rabbit, 2 mk2 jettas, 2 mk4 gti's, mid 80's vanagon gf has a mkv jetta 2.0t) in VCDS for EDC15 ALH cars the n75 value shows the percent the VALVE is CLOSED. so if you see 100% that means 0% vacuum is being passed -valve is fully closed, not passing any vacuum through, so vanes wide open, least boost. 0% means valve is fully open, full vacuum, for max boost. for MAS15 (wastegate cars - AHU) and EDC16 cars (BEW PD cars in VNT-15 should sustain 18.0 max. and spike no more than 21.0 PSI in a typical 1,500RPM-redline 3rd or 4th gear test. 28 PSI for 17/22? Seems a bit high. 26 PSI sustained was recommended by the original VNT-17/22 distributor a little while ago, and even that's a little high. 28 PSI is also close to the limit of 3 bar MAP. Mar 3, 2015. #10. Our daily driver runs 26 psi max on stock head bolts. Have around 15,000km on it so far after the upgrades and it has around 300,000km total. I don't hesitate to use the boost but don't beat on it hard every day or anything like that. If I ever take the head off I'd add ARP studs while in there. CZDpI. Re: GT1749VA Turbo 1.9 TDI problem with low press at high R. by brum » Wed Apr 06, 2011 12:51 pm. Big FMIC, higher air density after it. This means that the turbo has to pump more to achieve the same pressure. There is something strange in the logs. The N75 duty cycle is almost the same as the one in the first log. The tee-piece is a temperature sensitive valve that opens when the fuel temperature is below about 15 C / 60 F, and closes fully when above 25 C / 80 F - the purpose of this is to supply some heat to the filter during cold conditions, to resist the tendency for cold diesel fuel to "gel". stock turbos can take 1.6bar boost max reliably. more can be done but it will not last. The Ride: '09 Polo 1.9 TD i 96KW HighLine. Mods: Straight-flow FMIC ,Stainless boost piping, RKmotion tuned, 17" Audi A5 Reps, Cobra coilovers, SMF cutch kit. H&M Dyno Night: 114KW 429NM. A 90 hp 1.9 TDI engine with regular service can reach 500000 km, even if the driver likes to press gas. There are many variants and powers of the 1.9 TDI engine. The 1.9 TDI engine with 110 bhp and more is more expensive to repair and less variable-geometry turntable and flywheel. Guidelines for Higher-Boost Applications. To run boost levels from 6 to 10 pounds, Weiand recommends the following: Forged blower pistons with a static compression ratio of 7.5:1. Steel crankshaft. Four-bolt main caps. Steel harmonic dampener. Stainless steel valves. Three angle valve job to promote better cooling.
