(2) Goods are of acceptable quality if they are:
(a) fit for all the purposes for which goods of that kind are commonly supplied; and
(b) acceptable in appearance and finish; and
(c) free from defects; and
(d) safe; and
(e) durable;
as a reasonable consumer fully acquainted with the state and condition of the goods (including any hidden defects of the goods), would regard as acceptable having regard to the matters in subsection (3).
(3) The matters for the purposes of subsection (2) are:
(a) the nature of the goods; and
(b) the price of the goods (if relevant); and
(c) any statements made about the goods on any packaging or label on the goods; and
(d) any representation made about the goods by the supplier or manufacturer of the goods; and
(e) any other relevant circumstances relating to the supply of the goods.
Failure to comply with consumer guarantee - available actions
On the 3rd of September I was travelling was north bound on Bruce Highway when the motor started to shudder and blow a lot of smoke and loss of power pulled over off the road where the car started to misfire resulting in it unable to start over or hold revs.
Had the vehicle towed back to home address...where we proceeded to have the mechanic from Littles Automotive come out we believe it may have been the injectors mechanic took them to KM Diesel to have them tested which resulted in unclear results between the cylinders the car was towed to KM Diesels on Monday to have the compression tested in the motor which so far has resulted around $1000.
I am disappointed because the car has not performed well because the car had issues within the engine and is not driveable due to this, has been confirmed by a diesel specialist who conducted a compression test which has shown issues with cylinders 3 and 4.
To resolve the problem I would like you to repair the vehicle at no charge to me through VW service centre at Kippa Ring.
Enclosed are copies of the receipts and test results.
We removed the cylinder head as recommended, upon removal we have found the head gasket blown between cylinders #3 & #4, this has also caused damage to the cylinder head (blown out chunk between the cylinders) and has damaged the block surface and engine block surface. We also found valves have hit and engine timing out, so unsure on the full story on this engine and the work that has been done to it prior to the current failure. Our recommendation is a new or second-hand engine. Also, whilst working on the vehicle we have noticed vehicle has had its EGR and DPF removed/deleted, to do this means the car also likely has a chip tuned engine ECU.
(a) Mr Haigh confirmed that he inspected the vehicle on 17 October 2023, not on 26 April 2023 as incorrectly indicated in the assessment report.
(b) Mr Haigh does not know whether the engine problem was pre-existing before purchase. The emissions system having been blocked off, the vehicle was not operating as designed by the manufacturer in that the cylinder temperatures would have been higher and other systems would have been reading incorrectly, contributing to the engine failure.
(c) A roadworthy certificate should not have been issued with the emissions system blocked off.
(d) The emissions system includes a gas recirculation valve that puts gases back into the engine to be reburned so they're cleaner coming out of the exhaust. The DPS system catches the soot and burns it off at a higher temperature, so it doesn't pollute. These systems are interconnected with the engine, so when the emissions system is removed or blocked off, the engine receives the wrong signals, and it can inject more fuel at the wrong time and raise the cylinder temperatures resulting in valve and head gasket failures and burnt pistons, having a direct impact on the engine failure.
(e) The vehicle's emissions system was blocked off, not removed, because the passages were closed. This definitely happened before the sale of the vehicle, perhaps even before it was bought by the wholesaler. Mr Haigh could see that the work done was old work, it had carboned up, and there were no fresh tool marks.
(f) There are several reasons why an emissions system is removed or blocked off. The system's valves and coolers are very expensive. When they fail, they can cause engine damage, so sometimes they're removed as a preventative measure, however if not done correctly, it can cause problems. Removal is also motivated by a mistaken belief that it increases the vehicle's power. It is illegal to remove or modify emissions systems in Australia except in the case of farm vehicles.
(g) The vehicle requires a total engine replacement rather than an overhaul due to the damage done to the cylinder block and head. A replacement engine is more cost-effective; an overhaul involves stripping down the engine, replacing all associated non-serviceable parts, and rebuilding.
(h) The replacement engine could be second-hand if a suitable one is available. The downside is that the service history of a second-hand engine is unknown, and it can't be tested until it is installed in the vehicle. It is possible to go through two or three second-hand engines before getting a good one. If the replacement is a new engine, Volkswagen is best place to install because they know the vehicle, however any mechanic can do an engine replacement.
(i) The emissions system requires reinstallation, and the ECU computer system must be reprogrammed back to Volkswagen factory settings or replaced. The blanking plates need to be removed and the gaskets replaced; then it all needs to be cleaned and checked for serviceability because when blocked, the exhaust gases can't flow, and carbon sludges up the engine.
(j) This rectification work is very expensive, more so because the vehicle is a Volkswagen. It is possible that the rectification cost would exceed the cost of purchase. The vehicle has been sitting for a couple of years and may require other work. For example, old oil remains in the transmission, the tyres are likely dry rotted and flat spotted, and the battery won't hold a charge. Other parts may also not be serviceable due to being stripped down and stored in the vehicle's tray and cab attracting surface and flush rusting.
(k) Mr Haigh is certain the damage to the cylinder head and block was caused by the engine failure and not rust as a result of the vehicle being out in the weather for 10 months prior to his inspection. It is obvious that the emissions system had been blocked off, the cylinders overheated, and when the gasket blew, a 5 mm chunk blew out between the two cylinders.
(l) There could be signs of this type of engine failure. The vehicle could be idling rough or be low on power, however an unqualified person may attribute this to poor quality fuel. Mr Haigh believes the vehicle would have been overheating when the failure occurred due to extra fuel going in as a result of the emissions system having been blocked off. This would have increased the cylinder temperature, but not the coolant, so it would not have shown up on the dash. The problems encountered on the highway were due to lost compression in the cylinder, the engine running on three cylinders and losing power, and significant variations in the crank speed. The computer system going haywire was the vehicle trying to decipher the engine failure.
(a) the vehicle's emissions system had been blocked off prior to the Applicant contracting to purchase the vehicle from the Respondent.
(b) the vehicle was unroadworthy at the date the Applicant took delivery of the vehicle.
(c) the blocked-off emissions system contributed significantly, or completely, to the cylinder head failure.
(d) the vehicle's cylinder head failure caused the engine failure.
(e) the Respondent knew or ought to have known at or prior to the Applicant contracting to purchase the vehicle from the Respondent that the vehicle's emissions system had been blocked off.
(f) the Respondent did not make the Applicant aware of the vehicle's blocked-off emissions system at or prior to the Applicant contracting to purchase the vehicle from the Respondent.
(g) the Applicant did not become aware of the vehicle's blocked-off emissions system until he received the Keystone Volkswagen, Kippa Ring inspection report on 15 February 2023.
