Assuming the same deck height, T4 AXG-engine code pistons (VE injection) yield a CR of 19.0:1. T5 PD pistons bring it down lower still. The formula for determining the compression ratio is:\. CR = (clearance volume + swept volume) / clearance volume. For a stock bore- and stroke 1.9 TDI, each cylinder will have a swept volume of 474 cc (492 cc
0 Post (s) T4 2.5 TDI Oil Leak – 16-03-2010, 05:46 AM. Help! I have just moved to Texas for a few years and I shipped my 2002 T4. Unfortunately, it has a significant oil leak from the right hand side of the engine. I can not identify where the oil is coming from. It seems to be low on the block and appears to be coming from the rear of the block.
2.5 TDi 88 bhp. The Transporter T4 2.5 TDi 88bhp variant is an identical setup to the 102bhp but without the addition of a top mounted intercooler.

Power once remapped adds a very much needed boost to torque whilst aiding improvements to fuel economy. 304 satisfied customers. vw lt 35 transporter Vw lt 35 2.5 tdi trouble code 17660 p1252.

Hi, Im doing a 1.9 TDI conversion and needed to know what transmission codes and corresponding ratios go with them. We only had the 2.5 petrol engine with a REALLY low geared transmission and need something with a taller final drive. I can swap the 5th gear swap no problem, its just the other 4 gears..

VW T4 2.5 tdi Timing Belts Replacement Timing belts are a serviceable item (60k or 4 years) and should be considered imperative in the up keep of your vehicle! failure of any of the timing belt, tensioner pulleys or water pump will in most cases lead to catastrophic engine damage. In the manual, it states that the pump timing must be set up after the cambelt change. If any of you have done this job, did you manage to do it without messing up your pump timing?. I've been quoted £128.80 for a cambelt kit from a VW main dealer. Can an equivalent kit be bought elsewhere at a more reasonable price?. Check where oil level is on dipstick & top up as necessary so it sits just below the top/max notch. Run engine for a few mins to let filter fill up properly, and allow oild to flow around engine then turn off & leave oil to settle back into sump for 10mins. Then re-check oil level at dipstick & top up as necessary.

13. Oct 15, 2014. #1. My 2008 2.5 TDi California's engine has just seized on a trip back from Cornwall. :cry: The No 2 ports and cylinder seem to be completely mashed. It has done 64000mi and been dealer serviced most recently 2 months ago. They do not seem to have an explanation for this failure and are suggesting a new engine at £7300 plus VAT!.

2.5 tdi ajt pump timing. I've had this 2.5 tdi ajt since last august/september and it's always been a bit pants at starting, and when it does it smokes a lot. I figured out the pump timing was out, VCDS say too retarded. I went to adjust the timing with the pump tensioner / pulleys and I found that it had already been adjusted as far advanced

2002 T4 2.5 Tdi 75kw with auto box. I was cruising on the motorway when the engine suddenly died without any warking. Tried to start it but no joy, so had to get it towed home. Been doing the basic checks, but havn't found anything so far. Starter works and glow plug light comes on as normal
