20 Most Recent 2001 Volkswagen Beetle - Page 6 Questions & Answers

I'd try looking at the things they discuss on this page because they talk about wire damage to the O2 sensor and/or mass airflow sensor. If you can't find anything there I'd take it to a shop rather than start to replace parts hoping you pick the right one to change. http://forums.vwvortex.com/showthread.php?5847983-mk4-GTI-throttle-issues-EPC-light-engine-cut-out

DO NOT TURN IT OFF! It is indicating that there is possibly something wrong with your airbag deployment system. Get to a certified (where air bags are concerned) mechanic and have it checked out. PLEASE, do it SOON!

the anti theft has probably kicked in , see hand book for the procedure to restart or contact a vw dealer for the info

What engine ? Should be behind water pump on side of block.

Normally you need to replace the speedometer. Is it driven by a cable or is it electric/digital? There are suppliers that provide speedometers with miles and kilometers both available as a option, such as one bought in Germany to American specs purchased in Germany for reshipment to US, commonly available in instances where a tourist want a car to pick up in Germany, drive for awhile, the ship back to US.

Do you have an ABS light on as well?

Yes and no depends on the type of fuel pump is it a conventional type or a common rail ?

You should be well experienced in what to do with any vehicle problem CHECK FOR OBD CODES We have had these systems for 33 years Obviously the ABS Braking System has a problem

As you noted, a P1649 code is basically a communication error. It is generally caused by 2 things, either a short in the CAN bus data wires, there are 2 wires, wrapped around each other,Can high and Can low, or the central terminal resistor, which is located inside the ECM. You can test the wires for resistance or a short fairly easily with a good multimeter, but checking the resistor is more difficult, and requires a breakout box and a good scan tool. Might be a good idea to let a VW dealer or a good shop that specializes in VW to diagnose it and take it from there.

code p1649 refers to CAN data bus, ABS-- no signal==causes--ABS control module trouble /s stored , --wiring--matching resistor in ECM Check with a VW service centre as it may be a problem in the ECM connected to the ABS control module.

This mean the sensor is getting bad,you have to replace hub bearing.

Sounds like when they fixed the headliner they disconnected the power lead to the sunroof. Take it back to them and tell them to fix it; or go to a place that does sunroof repair and have them diagnose it; once you know what the cause is, you can go back to the upholstery shop and ask them if they will pay for the repair.

sounds as though you need a new alternator.

Check your coolant level. Is the car running normally otherwise? if it is low coolant, look for leaks. You can try topping it up with g12. Coolant and distilled water.

Hi. It is telling you that the engine is cold. It goes out after about 5 min of driving.

None. On some models the agents can code it out.

Hi Diaconnect the aftermarket radio if one is fitted. If the ABS light is on then disconnect the abs pump. These are the 2 most common reasons for this issue.

Hi Are there any faults stored. I would start with the spark plugs and checking for a misfire.
