The addr from my book is Robert Bentley, Publishers 1000 Massachusetts Ave. Cambridge, Mass. 02138 You can order direct, or via yer dealer, or via bookstore: ISBN 0-8376-0370-6 (2 books, about $100.00 - yikes!) 84-88 5KS including t, tq, diesel (yuck), wagon... Occasionally found in used bookstores... The relays for Aux panel 1 are # as follows: (applies to 1986 turbo/turbo quattro - ea # corresponds to a relay location) 13 14 15 16 17 18 1 2 3 4 5 6 7 8 9 10 11 12 1= ABS combi relay 2=open 3= Chime Warning Relay 4=Power Window/Sunroof control unit 5=Front lamp monitoring unit 6=Power Window relay 7=Idle Control 8=Idle Control 9=Idle control 10=Radiator Cooling fan, 3rd stage 11=open 12=Rear defogger 13=Seat heater control (passenger) 14=Seat Heater control (driver) 15=Injector cooling fan 16=circuit breaker for seat/windows 17=open 18=radio/parking light warning buzzer WRT checking codes: Does your fuel pump relay have a place to slip a fuse in (up on top)? ok... The codes are stored in memory, and are erased when you shut it off. There are input diagnosis checks, and output diagnosis checks. When you put a fuse in that spot on the relay (4 sec min), it kicks it into diagnosis mode. The little orange engine hurt light blinks twice, then blinks a 4 digit code, pauses, then repeats. For input diagnosis, you must bridge the contacts again to see the next code. When you get to 0000 then yer done. 86-88 turbo models (include quattro) Test conditions (input diag) - test drive 5 min, min 3000 rpm, 1.2 bar boost. bridge contacts, 4444 no fault in memory 0000 end of diagnosis (warning lite off for 15 sec after start signal) 1111 control unit defective mem ckts in control unit (bummer!) 2111 RPM sensor control unit not receiving signal 2112 timing ref signal control unit not recieving signal, distrib adj off 2113 Hall sending unit control unit not recieving sig, distri improp adj 2221 Vac hose to ECU leaking, plugged, disconnected 2222 Press sensor-ECU defective 2141 Knock control timing at max retard (or low octane fuel) 2142 Knock sensor defective or open ckt 2123 full throt switch defective or open ckt 2121 idle switch defective or open ckt 2312 engine temp sensor defective or open ckt 2322 intake air sensor defective or open ckt 2342 oxygen sensor defective or open ckt output diagnosis - checks each component. test condition - switch ignition off. Switch back on - do not start or crank engine (puts it back to input mode) bridge contacts code displayed 4433 - for fuel pump relay and pump - pump runs disconnect fuel pump (don't have to, damn good idea - otherwise you'll have full system pressure while you go through the rest of the checks :(... bridge contacts code displayed 4441 - for OXS freq valve - this is the dude that buzzes like a bee by the fuel distributor - valve buzzes bridge contacts code displayed 4442 - for wastegate freq valve - valve clicks bridge contacts code displayed 4443 - for cold start valve - cycles on/off 10 seconds (if you blew off disconnecting fool pump, you're now puddling fuel in yer intake...) bridge contacts code displayed 4343 - for charcoal cannister shutoff valve - valve operates. end - switch off ignition. You said something about a boost warning light. If this is the bottom middle engine light (or the light that blinks when you do these diagnostics), that is NOT a boost warning light - its yer ignition light telling you its got a problem... You should have the computer system that tells you miles to go, ave speed, boost etc.... You do have this, right? As we're getting into this, I think you're getting an error when you get to 3000 rpm, and thats what yer seeing... I'll post this to the list so other non Bentley owners can slip by another month or two until they give up and buy one... ********************************AUDI FAN****************************** EMCM(SW) Dave Head 87 5KCSTQ 170K miles and counting... 1.8 bar boost - @ 1.3 the shuttle launches Maitland FL **********************************************************************
