Iz iskustva naše radionice u Banja Luci - šta najčešće dolazi na popravku i na šta obratiti pažnju prije nego što se kvar pogorša.
- 01 /
Dual mass flywheel on 1.9 and 2.0 TDI
Idle vibration, knocking on engine start and stop, jerking when pulling away, metallic rattle when the clutch is engaged.
Uzrok /Dual mass flywheel wears out naturally - typically between 150,000 and 200,000 km on these engines, earlier if the car is mostly driven in city traffic.
Popravka /Replacement of the dual mass flywheel together with the clutch kit - always as a pair since the gearbox has to come out anyway.

Mali savjeti koji produžavaju vijek motora i smanjuju račune za popravku.
- 01 /
Change engine oil every 15,000 km, do not wait for the 30,000 km interval in the service book.
- 02 /
After motorway driving let a TDI engine idle for 30 seconds before shutting down, to cool the turbo.
- 03 /
If you mostly drive short city trips, take the car on the motorway for at least 30 minutes once a week so the DPF can regenerate.
- 04 /
Replace ignition coils and spark plugs preventively on TSI engines around 100,000 km.
- 05 /
Check the oil level between services on 1.8 and 2.0 TSI - these engines can burn oil silently.
- 06 /
First rattle from a 1.4 TSI cold start means immediate diagnostic - the timing chain will not wait.
- 07 /
Quality fuel and a fresh fuel filter every 30,000 km extend the life of injectors and high pressure pumps on diesels.

- Q /Where can I service my Volkswagen in Banja Luka?
- At Auto Gas Gaga on Njegoševa 44 we service all Volkswagen models since 1996. Call +387 65 701 308 to book.
- Q /Golf 5 and Golf 6 minor service price
- Price depends on engine type, oil grade and filters used. Call us for an exact quote, we work with reliable parts and no hidden costs.
- Q /Do you repair DSG gearboxes?
- Yes, we service DSG transmissions including oil and filter changes on 6-speed DSG and mechatronics diagnostics on 7-speed. We explain options before any major repair.
- Q /Do I really have to replace the clutch with the dual mass flywheel on a Passat B6?
- Yes. The gearbox has to come out to reach the flywheel, and replacing only the flywheel while leaving an old clutch will mean paying for the same labour twice within months.
- Q /How long does a 1.4 TSI timing chain replacement take?
- A full timing chain set replacement on a 1.4 TSI usually takes two working days. We recommend replacing the water pump and thermostat in the same job if they are original.
- Q /My Golf 7 2.0 TDI is showing a DPF warning, what should I do?
- First step is computer diagnostics to see if the filter is just clogged or if there are sensor faults. Most cases can be resolved with a forced regeneration; if the filter is fully blocked we remove it for professional cleaning.
- Q /Do you offer VAG diagnostics?
- Yes, we have professional VAG diagnostic equipment that reads all modules - engine, transmission, ABS, airbag, climate control, door electronics. Diagnostic time is 20 to 40 minutes.
- Q /Do you install LPG conversion on Volkswagens?
- Yes, we have been doing LPG installation, service and repair since 1996. Petrol Volkswagens are regular customers for LPG conversion.
