Please give copies to all your VW Technicians C 91--99--07 E 1999 Volkswagen of America, Inc. 1 Subject: Model(s): Group: Number: Date: AM Radio, Poor Reception 1999, 2000 91 99--07 New Golf, New Jetta, Aug. 2, 1999 New Beetle, Passat Condition AM reception is poor. May be caused by: ? An incorrect antenna mast installed for the antenna base equipped with the vehicle ? Poor ground at the antenna base or radio ? Poor battery ground to chassis or engine ? Poor antenna cable connection at Radio ? Corrosion at the antenna coaxial connectors at radio or antenna Service Vehicles are equipped with either a Bosch or a Clarion antenna base mounted on the roof and (for shipping purposes) the appropriate matching mast is located in the luggage compartment. If radio antenna masts are removed from vehicles and stored until vehicles are sold, there is a chance that an incorrect mast can be installed at the time of delivery. Note: Mismatched antenna mast and base will cause poor AM radio reception. The antenna base and mast can be identified visually as follows: (Cont. on Page 2)91-A260 requires gloss finish antenna mast 57mm 49mm Bosch 91-A261 requires matte finish antenna mast 61mm 41mm Clarion 91-A262 Technical Bulletin Important! Please give copies to all your VW Technicians C 91--99--07 E 1999 Volkswagen of America, Inc. 2 Bosch antenna ? Base (although oval) is more circular in shape (approx. 57mm x 49mm). ? Made in Germany stamped on underside of base. ? Two screws on underside of base are unpainted. ? Requires gloss finish antenna mast. Clarion antenna ? Base is more oval in shape than Bosch (approx. 61mm x 41mm). ? Two screws on underside of base are painted. ? Requires matte finish antenna mast. If antenna mast matches the antenna base correctly: -- Check antenna coaxial cable connections --arrows-- for corrosion and clean if necessary (DO NOT apply stabilant). Passat coaxial cable connection for radio is under the carpet on right side of tunnel near shifter. -- Ensure that coaxial cable is firmly seated in radio (Passat cable connection, see previous step). -- Check ground at the antenna below roof Nut --4-- (torque = 7+1 Nm) must firmly secure antenna to roof). (Cont. on Page 3)Technical Bulletin Important! Please give copies to all your VW Technicians C 91--99--07 E 1999 Volkswagen of America, Inc. 3 -- Check ground for radio behind radio on cross member (On Passat models as of Nov. 1998 beginning VIN: XE285000 ground for radio is on right side of center tunnel). -- Check engine compartment ground, left side, below battery tray; frombattery GND to body. -- Check engine/transmission ground on transmission, near engine block. -- If all grounds and antenna mast are OK. -- Replace antenna and coaxial cable assembly

thats the only way i am a vw tech and have had to change this there is no other way the sunroof assembly needs to come out to do this properly

I was having the same problem with a jvc kd hdr 30. I Installed it myself over a year ago and never wanted to deal with the issue. Finally, I decided to take a look at it today.
On my head unit, all wires were connected except one blue one with a tag that says "do not connect to power, for remote device or power antenna only." This unit is in a '97' MBZ E320 with no visible antenna; I think it is part of the windshield. In any case, between the wiring diagram in the manual and the harness that is part of my car, I was left with 2 blue wires to choose from, one with a white stripe and one with a gray stripe. After testing both for power or ground, I determined neither had power with key on or off. Both had high resistance ground when compared to the chassis ground. In other words, I measured between chassis and these wires. First, I took a wire and connected it to the chassis ground and connected the other end to the blue wire coming from the unit while tuned to a local am station. This simply killed all reception am or fm but did not harm the unit. Next, I connected the blue wire with gray stripe of the car harness to the blue wire of the unit and again this killed all reception. Then I connected the blue wire with white stripe of car harness to the blue wire of unit and presto magic I had great am reception.
I am guessing that this blue wire with white stripe must be part of the antenna itself or perhaps is a connection that increases antenna power. Maybe 'power antenna' on tag refers to an actual powered antenna (like as in amplified?) and not as in an antenna that rises up out of fender, as I believed.
This may not help the first person with the question, but maybe it will help someone out there who searches for these kinds of answers like I do from time to time.

Shouldn't need one. Does the rear antenna connect to the direct FM box?

Hi

If the coolant temperature sensor is of the 4 wire type then these are a common failure on VW's.
