New direction on injection
After my complaint about the rattling engine in my 2011 Volkswagen Golf diesel appeared in your column VW contacted me and they took my car in for rework. They oversaw the work at the dealership and gave technical assistance. I picked it up just before Christmas after all four injectors were replaced with some computer upgrades and the car is running fantastically. Mick and Cathy Morris, email Glad to help. It’s also nice to know VW’s on the case.
Sometimes I fill up with E10, sometimes when I am feeling wealthy I use 98 RON. Once when empty I filled up half E10 and half 98 RON. Is there any harm in mixing fuel? Richard Kenna, NSW. No, you’ll end up with an octane rating between the two fuels depending on how much of each you used. E10 has an octane rating of at least 94, so it’ll be between 94 and 98.
FOR CHRYSLER’S SAKE
I thought I would update you since I last wrote to you about the headlight fogging on my Chrysler SRT V8. After you responded I contacted Chrysler, but did not get far with either the dealership or Chrysler Australia’s customer service team, so I wrote to the CEO who passed my letter to the customer service team! I still have no resolution to my headlight fogging light problem, or the problem I also raised with them about the satnav voice recognition not working. A Chrysler customer service officer told me in August the satnav voice recognition problem should be fixed within two weeks, but have since been told the voice recognition did not work in Australia. Then in December they told me they were still looking into the issue and did not know how long it would be! I was also told they had contacted VicRoads who had told them the fog in the headlights was not a problem. The customer service officer also told me he was awaiting a response from the NSW RTA. He also reinforced the Chrysler technical section’s advice that if the headlight mist cleared within 20 minutes there was no need to change/replace the lights. I said they had a legal obligation to fix defects under warranty. I feel Chrysler is fobbing me off and not living up to its claim they value feedback. Dave S, email The headlight issue has reached a stalemate. You say it’s a problem, Chrysler says no. If you wanted to take it further you could consult a licensed VicRoads engineer and get an independent opinion. You can get a list of the engineers from VicRoads. As for the satnav voice recognition issue, keep on their case.
My 150,000km 2007 Toyota Prado GXL was jittering and knocking badly. If the engine was started on a slope it would blow copious amounts of white smoke, so I took it to Toyota who couldn’t diagnose problem. I then took it to an independent mechanic who thought the injectors were the problem and suggested taking it to a specialist diesel outfit, who diagnosed injector issues. In your experience is this a common problem in diesel Prados of this model. Eleanor Fairbairn, email It’s not unusual for them to have injector issues, which usually shows up by heavy knocking when the engine is cold and is fixed by replacing the injectors. If it only occurs on a slope, however, I would be making sure it isn’t an oil pickup problem, and I would have the oil pick-up in the sump checked to make sure it isn’t partially blocked.
