And so of course the cam failed and the engine started complaining loudly. I looked into getting a new cam shaft and cylinder head only, but I decided to replace the whole dang engine. Found an engine in a totaled 2006 Jetta TDI with only 130K miles for $1500, so I am going to drop that into my Jetta but I am also going to replace the cam and VIN position 5 is the engine code: F = 2.5 liter 5-cylinder G = 2.5 liter 5-cylinder T = 1.9 liter 4-cylinder TDI J = 2.0 liter 4-cylinder FSI (from 2006 model year) VIN position 6 is the restraint system: 2 = Varies with model year VIN positions 7-8 are the model type: 1K = Jetta VIN position 9 is the check digit: 0-9 or X calculated by NHTSA The TDI years to avoid are 2005, 2009, 2010, 2011 and 2012. Some common problems include- oil leak, injector failure, timing belt failure, clogging of EGR valve etc. Reading this article, you will find out which years have the worst problems. You will also be able to pick the best TDI engines based on non-problematic model years. Re: T25: Cost/Benefit of 1.9 AAZ or 1.9 TDI engine replacement. by scimdiesel » 08 Aug 2014, 14:43. Costs. Thats to open ended question. £4k to £4. If your JX motor is sick the AAZ is a good replacement. If its not, the difference may not be worth the sweat. Finding a good AAZ is not easy anymore. The basic 1.9 engine used them in all engine codes from the 1990's until around 2010 and it was fitted to many VW,Audi,Skoda and Seat cars and likely several millions of units. The only engines that seem to have a pronounced mention in forums seem to be the 105hp BXE and BLS engines fitted from around 2006-2010. The Audi A4 (B5) 1.9 TDI 90 has a Inline 4, Diesel engine with 1896 cm3 / 115.7 cu-in capacity. How many horsepower (hp) does a 1995 Audi A4 (B5) 1.9 TDI 90 have? The 1995 Audi A4 (B5) 1.9 TDI 90 has 90 PS / 89 bhp / 66 kW. VW engine codes will also follow. Any feedback, comments, and addition/change recommendations would be appreciated.

A little late to the party, but wanted to note that this engine (owned one in a 95 golf) runs on exactly one wire once it is started - the power to the fuel shutoff solenoid. Other than that, the engine requires exactly zero electrical power to run. b9PUB2.
