2006 A4, B7 (2.0 Liter, BPG engine) ---timing chain broke,

2006 A4, B7 (2.0 Liter, BPG engine) ---timing chain broke, and damage to pistons and camshaft "carrier." Replaced engine with a 2007 BWT and I used electrical harness from my old BPG engine. Now car cranks strong. but will not start. No spark at coils. I can hear the fuel pump with the key in the "on' position. I thought crankshaft position sensor---replaced the one in the BWT engine with the sensor from the BPG engine---no difference. I've checked all fuses in the dash side panel and the fuses in the ECM. I have double checked all my connectors. Battery is 4 years old but voltage measures at 13 volts. Al cabin and dash lights are working-I haven't yet connected the the headlights.JA: Have you checked the fuses? The dashboard bulbs?Customer: YEs, all fuses are good, including in the ECM compartment. I did have to splice an electrical connector for the alternator--not the heavy gauge wire output, just the small 2 wire connector which I suspect gives voltage reading to the dash.JA: Are you fixing your A4 yourself? What have you tried so far?Customer: I checked CKP (crankshaft sensor)----resistance is 872 ohms, the old one is 859 ohms. If I am doing it correctly, the output voltage from the CKP with a friend cranking the engine, is 2.7 volts. Same reading for both CKPs---At this time I cannot afford a ross-Tech type scanner. Is my best option to buy a new (Bosch) CKP?JA: Anything else you want the mechanic to know before I connect you?Customer: I do not have a diagram for the under dash relays, so I haven't tested them.

I have a 2007 A4 2.0T with 121K miles. The car is burning

I have a 2007 A4 2.0T with 121K miles. The car is burning oil at a fast rate. The last three times I added a quart, I got 418 miles, 636 miles (unusual - for me - round trip from Hartford to NYC and a 100 mile in-state round trip), and 359 miles. I've been reading about problems with piston rings with this model, and am concerned that may be the cause, or perhaps the valves (or maybe a combo). The engine has good power, with occasional blackish smoke under heavy acceleration. The car looks new, inside and out. If the garage/dealer were to recommend a valve job and piston ring replacement, would I be better off just driving it until it starts running rough (query, how long that may be), and then getting a remanufactured or new engine for the car? The camshaft was replaced under extended warranty at 117K (shortly after which the oil consumption increased by about 50%). The turbocharger was replaced one year ago. I have dropped about $6K in engine-related repairs in the car over the past 2 years. Your thoughts?Paul

I have an Audi a4 1.8t. It is making a ping noise. Pulled up

Hi I have an Audi a4 1.8t. It is making a ping noise. Pulled up codes p0333 and p0328 for the knock sensors. I got it yesterday and it had a slight noise to it. Thought it was just the natural sound of the motor. I made a mistake of putting regular low octane fuel in it and it got a lot worse. I put octane booster in and immediately refueled with high octane fuel. It's still making the noise. What should I do?
